I totally get why you want to break that game! However...The mistake you made was doing the packing when he didn’t! I know you were totally frustrated-why wouldn’t you be!- but by doing the packing yourself, you’ve got him out of a hole. Yes it does sound as though you have three kids, but when you mother him, he’s not going to “grow up”. He sounds like a procrastinator-I’m one, as you can guess by my name- and it’s only by being left get on with things ourselves, without someone coming along to do what we should have done, that we’ll cop ourselves on and focus on the task in hand. If you had just gone to bed with the packing undone, what would have happened? If it was still undone the next morning, you turn a blind eye and get stuck in with the children. If he made a comment re the packing, your reply would be “Oh yeah, I was wondering when you were going to do it”. What you DONT do is do it for him. So what if you’re not ready when the removal van comes? Your husband needs to be taught a sharp lesson and quickly. You’re his partner, not his parent, and you will not be picking up the pieces when he wastes time watching Netflix or playing a game. Both are addictive-I’d waste hours binge watching Netflix or playing a ridiculous game on my iPad/phone, and I put up timers and draw up lists to focus me and get jobs done.
As for needing time to yourself-don’t wait for him to volunteer, and don’t get emotional. You tell him that you are doing x,y,z, and he’s in charge of the children. I’m really sorry he’s acting such a gobsh*te, especially at his age when you’d expect him to be a bit more mature. However, if you love him and want to stay in a relationship with him, you need to start thinking of him as your “equal” and therefore someone who has to get tasks completed whenever and however he does them, and take charge of the children whenever you decide (initially, as hopefully, as time goes by, he’ll realise he’s the children’s other parent, rather than a quasi sibling!). Above all, stay calm and unflappable-difficult though that is in the face of someone else’s time wasting. Don’t get emotional when things aren’t done/he’s not engaging with the children. Tell him you’re doing whatever, walk away and let him get on with it.
Best of luck with things. Hope that your move goes well and that you4 new home will signify a new beginning in a new and more equal partnership.
